Abstract

A moving object detection apparatus is disclosed and includes a TV camera for capturing images in a monitoring zone. An image changing area is defined within a rectangular region, and is extracted from image signals corresponding to the images captured by the TV camera. From the image changing area, horizontal projective data is obtained. The horizontal projective data is compared with a standard horizontal projective data corresponding to a standard moving object to distinguish the moving object.
